Abstract

L'INVENTION SE RAPPORTE A UNE GEOMETRIE NOUVELLE DE PROFIL DE PLAQUETTES DE COUPE ET AUTRES MATERIELS DE COUPE EN CERAMIQUE OU EN CERMETS. CE PROFIL SE COMPOSE D'UN PREMIER CHANFREIN A CLASSIQUE DE PROTECTION D'ARETE; D'UN SECOND CHANFREIN B DESTINE A DIRIGER L'EFFORT VERS LE CENTRE DE LA PLAQUETTE OU AUTRE MATERIEL CONSIDERE; ET D'UN MUR C DESTINE A ENROULER LE COPEAU. L'INVENTION EST APPLICABLE A LA REALISATION DE PLAQUETTES DE COUPE OU AUTRES MATERIELS DE COUPE EN CERAMIQUES OU EN CERMETS.THE INVENTION RELATES TO A NEW PROFILE GEOMETRY OF CUTTING INSERTS AND OTHER CERAMIC OR CERMET CUTTING MATERIALS. THIS PROFILE CONSISTS OF A FIRST BEVEL A CLASSIC OF ARETE PROTECTION; OF A SECOND CHAMFREIN B INTENDED TO DIRECT THE EFFORT TOWARDS THE CENTER OF THE PLATE OR OTHER CONSIDERED MATERIAL; AND A WALL C INTENDED TO WIND THE CHIP. THE INVENTION IS APPLICABLE TO THE MAKING OF CUTTING INSERTS OR OTHER CUTTING MATERIALS IN CERAMICS OR CERMETS.

de l'arête.of the ridge.

La géométrie nouvelle de profil de plaquettes de coupe en céramiques ou en cermets selon l'invention se caractérise essentiellement en ce qu'elle se compose d'un chanfrein de protection d'arête classique sur les plaquettes de coupe céramique; d'un second chanfrein de grande valeur destiné à diriger l'effort de coupe vers le centre de la plaquette; et d'une partie droite ou rayonnée formant un mur destiné  The novel profile geometry of ceramic or cermet cutting inserts according to the invention is essentially characterized in that it consists of a conventional edge protection chamfer on the ceramic cutting inserts; a second chamfer of great value for directing the cutting force towards the center of the wafer; and a straight or radiated part forming a wall intended

à enrouler le copeau.to wrap the chip.

D'autres caractéristiques et avantages de la  Other features and benefits of the

présente invention ressortiront de la description qui  present invention will emerge from the description which

Sur le schéma représenté, la géométrie nouvelle de profil de plaquette de coupe en céramique ou en cermet montre un premier chanfrein A classique de protection d'arête, un second chanfrein B destiné à diriger l'effort de coupe et de préférence le plus possible vers le centre  In the diagram shown, the new geometry of ceramic or cermet cutting insert profile shows a first conventional edge protection chamfer A, a second chamfer B intended to direct the cutting force and preferably as much as possible towards the center

de la plaquette et un mur C destiné à enrouler le copeau.  the wafer and a wall C for winding the chip.

Le second chanfrein B est, de par sa destination, de grande valeur et sa valeur angulaire par rapport à la face d'attaque peut être comprise entre O et 30 par  The second chamfer B is, by its destination, of great value and its angular value with respect to the leading face can be between 0 and 30 by

exemple.example.

Pour la valeur 0, le chanfrein (B) constitue  For the value 0, the chamfer (B) constitutes

alors un méplat parallèle à la face d'attaque.  then a flat parallel to the leading face.

Le mur C est, dans l'exemple choisi, constitué par une partie droite mais il peut être, en variante, constitué par une partie rayonnée selon un rayon de plus ou moins grande valeur, suivant l'enroulement et le  Wall C is, in the example chosen, constituted by a straight part but it can be, alternatively, constituted by a radiated part according to a radius of greater or lesser value, according to the winding and the
